“…Figure 1 shows the molecular structures of monolayer forming compounds and anesthetics used in this work. Ultra pure water with conductance of <0.07 S/cm was obtained from a Super Water Purifying System (WL-21P; Yamato Scientific Corp. Ltd., Tokyo, Japan); the water was boiled for 10 min and subsequently cooled to room temperature [21,22]. The concentration of each anesthetic in aqueous solutions was 4 mM.…”

“…In this communication, we report physisorption interactions between two phospholipid monolayers DHP and DPPC and two anesthetics halothane and enflurane using a highly sensitively improved 6 MHz QCM device with a stability range ±0.5 Hz for > 12 h. A quartz crystal oscillator (QCO) was attached [21,22] horizontally to the monolayer formed at water surface. The artificially prepared phospholipid monolayer proved to be a good model that allowed to study a real living phenomenon including anesthesia.…”

We have investigated the interactions between phospholipid monolayers and volatile anest-hatics. Two monolayers (dihexadecyl phosphate (DHP) and dipalmitoyl phosphatidyl choline (DPPC) and two anesthetics (halothane and enflurane) were used to observe these interac-tions using a highly sensitive quartz crystal microbalance (HS-QCM). The concentration of each anesthetic in aqueous solution was kept at 4 mM. The frequency of QCM showed no change when halothane was added to the DHP monolayer, however, it responded and de-creased when interaction occurred with DPPC monolayer. In case of enflurane addition the frequency decreased in both the monolayers of DHP and DPPC. The frequency change followed the following order of monolayer-anesthetic interactions: DHP-halothane <DPPC-halothane <DHP-enflurane <DPPC-enflurane. These re-sults showed that the response of anesthetics to the monolayers i.e. the physisorption not only depends on the anesthetic structure, the type of anesthetic hydrate formed, but also the hydrophilic polar group structure of the monolayer or the monolayer/water interface had an important role in physisorption

Since the publication of the original review of piezoelectric acoustic sensors in this series there has been a consistent, gradual expansion in the number of published papers using 'quartz crystal microbalances' (QCM). Between 2001 and 2009, the number of QCM publications per annum has increased from 49 to 273, with a two-fold increase in papers per annum between 2004 and 2008. Within the field, comparing the time covered by the current to the previous review, there are trends towards increasing use of QCM in the study of protein adsorption to surfaces (93% increase), homeostasis (67% increase), protein-protein interactions (40% increase) and carbohydrates (43% increase). New commercial systems have been released that are driving the uptake of the technology for characterization of binding specificities, affinities, kinetics and conformational changes associated with a molecular recognition event. This paper highlights theoretical and practical aspects of the principles that underpin acoustic analysis, then reviews exemplary papers in key application areas involving small molecular weight ligands, carbohydrates, proteins, nucleic acids, viruses, bacteria, cells and membrane interfaces.
